IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 205,935, dated July 9,1878; application filed March 16, 1878.

To all whom it may concern:

Be it known that I, WILLIAM MEREDITH WHITELEY, of Joplin, in the county of Jasper and State of Missuri, have invented a new and valuable Improvement in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figures 1, 2, and 4 of the drawings are side views of my improved pump, the latter partly in section. Fig. 3 is a longitudinal vertical section of pump-barrel, with its pipes partly in section; and Figs. 5, 6, and 7 are detail views of the valve.

This invention has relation to improvements in pumps for wells, cisterns, and mines.

The object of the invention is to devise a pump for the purposes mentioned that will discharge a continuous stream from a nozzle or spout.

The nature of the invention will be fully set forth hereinafter.

In the accompanying drawings, the letter A designates a strong metallic barrel, having at its lower end a supply-pipe, B, closed by a valve, a, opening upward. B B designate two properly-packed unvalved pistons arranged in the barrel A. The piston-rod G of the piston B is tubular, and that O of piston B solid, and carried up the rod 0, as shown in Fig. 3. They are connected by pitmen D to the opposite arms I) b of a double-crank shaft, E, operated by a suitable mechanism to cause the said pistons to approach and recede from each other. F represents a metal tube, opening at its lower end into the supply-pipe below its valve, and at its upper end into the pumpbarrel at the space between the pistons B B aforesaid. The tube F has at a point on a level with the valve to of the supply-pipe a valve, a, opening upward. Opposite the point of entrance of the tube F into the barrel a second pipe, G, enters, that curves upward and enters the discharge-pipe G. The pipe G has also a valve, 0, opening upward.

It will be observed that there are three chambers in the barrelone above the piston B, one below the piston B and the third between them.

H represents a pipe, opening at its lower end into the chamber d, and connected by means of a short coupling, I, with the upper chamber. The pipe H is provided with a valve, f, opening upward at a point above the coupling I, and is carried to the main discharge-pipe by means of an elbow, J. Diametrically opposite pipe H is another pipe, N, opening at one end into the chamber 01, and at the other into the chamber 01 This pipe is auxiliary to pipe H, and may sometimes be dispensed with. In this case pipe H should be of greater capacity.

The operation of my improved pump is as follows: When the pistons recede from each other a vacuum is formed in the chamber (P, the valve to is opened, and water rushes up the pipe F into the chamber 01, aforesaid. At the same time the air and water in the chambers d d are forced, through the pipes H and N, valve f, and elbow J, into the dischargepipe G, above its valve 0. When the pistons approach each other the valve a of pipe F closes, and that, c, of pipe G opens, and the water is forced out of the chamber cl, through the valve 0, out of the discharge-pipe. At the same time vacuums are made in the top and bottom chambers d 6?, valve a opens, and water rushes up the supply-pipe B into the chamber 61*, and, through the pipes H and N, into the chamber d. When the pistons again recede from each other the water in the chambers d d is forced out, the former, through connection I and valve f, into the discharge-pipe G, and out of the latter, through pipes A N and the said valve f, also into the said discharge-pipe.

It is evident from the above description that this arrangement of pipes and valves in connection with a pump-barrel and the un- Valved pistons, operating as set forth, produces a pump of exceptional excellence for discharging water continuously. It is also evident that, by the use of a condenser or condensers in connection with the discharge-pipe G, the lifting-pump is converted into an excellent force-pump for many purposes.

In practice, the valves or a c f will be of any of the usual forms of clacks where clear water is to be pumped; but where muddy water or water and sand mixed are to be raised,I prefer to use a valve of the following description: It consists of a metallic seat, M, having at each side of its opening 12 a vertically-slotted post, 0, and ot' a valve, N, having journals i, that engage the slots n of the posts 0. The valve is of metal, and is provided with a leather or rubber facing, 11. When the valve is raised by the upward flow of water, the journals 1' ascend the slots n, thereby causing the said valve to assume a nearly vertical position, when the silt, sand, or mud will run back through the opening in the valve-seat, and prevent the valve from clogging. The valve is prevented from tilting over by means of a stop, s, projecting inward toward the center of the opening in the seat.

What I claim as new, and desire to secure by Letters Patent, is-

I. In a double-action pump,the combination, with the pump-barrel A, having a supply-pipe, It, with upwardlympening: valve 11 and the unvalved pistons, approaching to and receding from each other alternately, of the pipe F, opening at one end into the pump-barrel between the pistons, aud at the other into the supply-pipe below its valve, the dischargepipe G, opening into the pump-barrel opposite pipe F, and provided with valve 0, the pipes 11 N, opening into the upper and lower chambersof the pump-barrel, the valve f in pipe II, and a connection between the pipes H and G above the valve of the latter, substantially as specified.

2. The pump-valve consisting of the seat, M, having stop 8 and vertically-slotted posts 0, and the plate N, havingjournals i, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
